Great White Shark

The great white shark is the largest predatory fish on the planet. The way its teeth work is somewhat reminiscent of a revolver and they consist of several rows. When one of its sharp, triangular teeth breaks out of the front row, it is quickly replaced by another from the row behind it. New replacement teeth are constantly growing.

Fun fact: The teeth of the great white shark are 6 to 7 cm long and have jagged edges.
